Pregnant women experience many physical changes owing to the change in levels of hormones. As the body continues to adjust to the developments, there is an increased risk of UTIs. These infections could then go on to cause infections of the kidney or Pyelonephritis.

What is Pyelonephritis?

In simple terms, Pyelonephritis is the infection of the kidney. The infection is usually bacterial. Pyelonephritis can be of two types – acute and subacute, or chronic. Acute pyelonephritis is the sudden and severe onset of an infection of the kidney and is usually seen in pregnant women. This happens due to a range of reasons with the main one being the fluctuation of hormone levels.

Causes of Kidney Infection During Pregnancy

Pyelonephritis occurs when an E.coli infection occurs leading to the inflammation of the kidney and pelvis. The infection could occur due to:

Enlargement of the Kidney

During pregnancy, progesterone is released in high volumes, causing the smooth muscles to relax and the uterus to dilate in order to accommodate the growing foetus and placenta. This retards the flow of urine, and in some cases, it stagnates and backs up into the kidney. The kidney then enlarges to allow for the bacteria to multiply and cause an infection.

2. UTI

With the uterus pressing down on the ureter and bladder, the pregnant woman is more susceptible to infections of the urinary tract or UTIs. These infections can then travel up the ureter and infect the kidney.

Signs and Symptoms

The signs of pyelonephritis are usually manifest a few days after the infection occurs. The symptoms depend on whether you have acute or subacute pyelonephritis.

Acute Pyelonephritis

Severe pain in the abdomen and pelvic regions

Loss of appetite

A headache

High fever

Tenderness of the kidney

Bloody or cloudy urine

Vomiting and nausea

2. Subacute Pyelonephritis

Mild abdominal pain

Pain in the lower back

Fluctuations in body temperature

Vomiting

Infrequent chills

Frequent urination

Diagnosis and Tests

The diagnosis of acute pyelonephritis will be done after your doctor takes your full medical history. Some of the methods used for diagnosis that your doctor will recommend include:

Urine Tests

Upon a physical exam, if your doctor suspects any problems with the kidneys, then she will ask you to get a urine test done. The test will show up any signs of infection that you may have.

2. Imaging Tests

Imaging tests will be recommended to find if there are any obstructions in the urinary tract that is causing the stagnation and backing up of urine. These tests can determine the presence of cysts or tumours.

3. Blood Test

Your doctor might ask you to get a blood test in order to determine the extent of the infection. Once this is determined, your doctor will be able to develop the ideal treatment plan.

Complications Associated with Kidney Infection

Acute pyelonephritis during pregnancy must be given the right medical attention as soon as possible. If it is left untreated, then the following complications might occur:

One of the first things that could happen if pyelonephritis is left untreated is the scarring of the kidney, which could lead to high blood pressure and kidney failure.

With the kidney not functioning at an optimum level, there are increased chances of blood poisoning. The bacteria infecting the kidneys could enter the bloodstream in this condition and cause blood poisoning.

The infection could also enter the amniotic sac and fluid causing an infection. This could lead to the rupturing of the sac and a preterm delivery.

Preterm delivery will result in complications for the baby’s health including a low birth weight.

In some cases when pyelonephritis is accompanied by a high fever, there could be a miscarriage.

How to Treat a Kidney Infection

If you are diagnosed with acute pyelonephritis during pregnancy, then you will be admitted to the hospital where the first round of treatment is IV antibiotics. If you do not respond to this treatment, then you will be given stronger antibiotics in order to kill the infection.

However, if the infection is caused due to an obstruction such as kidney stones, then the treatment will aim to ease the pressure on the kidneys.

Once you are discharged from the hospital, you will have to continue to take oral antibiotics for ten days. If you develop pyelonephritis during pregnancy then the chances of it reoccurring is quite high. You might be recommended to take a low dosage antibiotic every day for the rest of your pregnancy until the pressure from the uterus eases.

What Should Be the Outlook After Treatment?

Pyelonephritis needs to be monitored after treatment too. Here is the post-treatment care and monitoring you will need:

Screening

After you have been treated for pyelonephritis, your doctor will continue to screen you for any possible reoccurrence of the infection during your regular prenatal routine check-ups. This will include checking on the health of the baby as well as urine tests.

2. After Delivery

Even after delivery, you will have to be screened for the occurrence of the infection of the kidney. While the uterus will no longer be applying pressure on the urinary tract and the hormones would have settled down to the normal levels, there is still a possibility that you will continue to have issues with the kidney depending upon the extent of the initial infection and how soon it was treated.

3. For the Baby

If the pyelonephritis is not treated in a timely manner, the infection could affect the amniotic sac leading to preterm delivery. In such a case, the health of the baby will have to be closely monitored in the initial months in order to ensure that all systems including the immune system are fully developed with no lasting ill effects.

Simple Home Remedies to Cure Kidney Infection

While you do need medical attention to take care of the infection, there are certain home remedies that you can try.

Drinking cranberry juice will make the urine more acidic and help flush out and kill the harmful bacteria.

Yogurt is not only an excellent source of antioxidants, it also hosts a whole plethora of good bacteria which will then proceed to kill and inhibit the growth of the bad bacteria causing the infection.

You must incorporate foods that are rich in Vitamin C into your diet. This includes citrus fruits, potatoes, and strawberries.

Juice a bunch of parsley and have it every day in the morning to help flush out the bacteria.

Marshmallow roots are known to be a good diuretic and will help cleanse the kidneys.

If you are prone to UTIs then you must consume some amount of apple cider vinegar every day as it neutralizes infections as well as restores the pH levels in the body.

Another great diuretic is garlic.

Echinacea reduces the swelling of the urethra and will make urinating less painful.

Celery seeds are well known for their antibacterial and antifungal properties.

Prevention of Kidney Infection

There are many steps you can take in order to avoid a kidney infection during pregnancy. Some of them include:

Keeping yourself well hydrated by drinking 8-10 glasses of water every day. This will ensure that your kidneys work at the optimum level.

Practising good hygiene especially around the genital area.

With the opening of the urethra so close to the anus, it is important to clean the area well.

Use soaps and other products that are mild and hypoallergenic.

If you do have an infection, then avoid coffee and alcohol.

FAQs
